Copper-Silver-Gold Alloy

The invention relates to a copper-silver-gold alloy for an electrical, electronic and/or electrotechnical component and/or for a device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission . The invention also relates to the use of this alloy in an electrical, electronic and/or electrotechnical component and/or device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, and the invention relates to a corresponding electrical, electronic and/or electrotechnical component and/or device comprising this alloy. Finally, the invention relates to an electrical, electronic and/or electrotechnical component or a corresponding component which has this alloy.

In devices for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, for example for music reproduction, recording and/or processing, for example in loudspeakers, amplifiers, sound signal sources, microphones, pick-ups , for example guitar pick-ups, mixers and cables and/or components for these, the composition of the metals and metal alloys used in them, for example in an electrical, electronic and/or electrotechnical component, can have an influence on the timbre of the received sound and/or processed tone.

However, the metals and alloys known in the prior art are not yet optimally formed. Thus, although a warm timbre can be achieved through the use of pure copper in electrical, electronic and/or electrotechnical components in such devices, the timbre that can be achieved in this way has no transparency. Although the use of pure silver in electrical, electronic and/or electrotechnical components in devices of this type allows a timbre with a high level of transparency to be achieved, the timbre that can be achieved in this way is also cool at the same time. However, in some areas of application, for example to achieve a certain sound impression and/or in the reproduction, recording and/or processing of sound, such as music and/or speech, it can be desirable to have a timbre with both a high degree of warmth and a certain To achieve radiance and elasticity, which is achieved by the metals and alloys known in the prior art, in particular when used in an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or line, for example for music and/or voice playback, recording and/or processing, has not previously been possible to a sufficient extent.

The invention is therefore based on the object of designing and developing the alloy mentioned at the outset, the use mentioned at the outset and the component or component and/or device mentioned at the outset in such a way that the alloy when the alloy is used in an electrical, electronic and/or electrotechnical component or in a corresponding component and/or in a device for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, in particular for music and/or speech Reproduction, recording and/or processing that allows the achievement of a timbre with both a high warmth and a certain radiance and elasticity.

The object on which the invention is based is achieved by the copper-silver-gold alloy with the features of patent claim 1, the use with the features of patent claim 6 and the corresponding component or the corresponding part and/or device with the features of patent claim 9 or patent claim 12.

- >90.00% by weight to <99.98% by weight copper, for example >99.70% by weight to

< 99.98% by weight copper, for example > 99.85% by weight to < 99.95% by weight copper,

- >0.01% to <5.00% by weight silver, for example >0.01% by weight to <0.20% by weight silver, for example >0.04% by weight to <0.10% by weight silver, and

- >0.01% by weight to <5.00% by weight gold, for example >0.01% by weight to <0.10% by weight gold, for example >0.01% by weight to <0.05% by weight gold. In particular, the alloy can be used for an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or conduction, for example for music and/or voice reproduction, recording and/or processing, be designed or used, in particular the corresponding electrical, electronic and/or electrotechnical component be at least partially made of this alloy, in particular an electrical line, a conductor track or a connection element consist of this alloy. In particular, the alloy is electrically conductive and can therefore itself be used or employed as an electrical component and/or in particular as part of an electronic and/or electrotechnical component and/or device.

Such a composition of the alloy can advantageously, especially when the alloy is used in an electrical, electronic and/or electrotechnical component for sound reproduction and/or recording and/or for sound signal processing, output, reception and/or transmission, for example for music and/or speech reproduction, recording and/or processing, a timbre can be achieved which is both warm and has a certain radiance and elasticity.

As is customary in connection with alloys, wt. % can also be understood in the sense of the invention in particular as a percentage by weight, ie a percentage by weight or mass, which relates to the total weight of an alloy. A specification in percent by weight (% by weight) differs in particular from a specification in atomic percent (A%), which is also used in connection with alloys, in particular by which a percentage of the atomic number is understood, based on the total atomic number of an alloy can.

In the sense of the invention in connection with the alloy composition, the term “comprise” can be understood in particular to mean that the alloy can contain other elements in addition to the elements specified.

The term "exist" can be understood in the context of the invention in connection with the alloy composition, in particular that the alloy contains traces of other elements in addition to the elements specified in amounts that are usual for impurities in alloys, for example in the mass-related ppm range, for example from <0.0050% by weight, e.g. <0.0040% by weight, e.g

<0.0030% by weight, in particular in each case per other element.

<0.05% by weight gold, the remainder being up to 100% by weight formed by copper and, in particular unavoidable, impurities. The impurities, which are particularly unavoidable, can, for example, be traces of other elements in amounts that are typical for impurities in alloys, for example in the mass-based ppm range, for example <0.0050% by weight, for example from

<0.0040% by weight, for example <0.0030% by weight, in particular in each case per other element.

But there are also other possible uses for the alloy according to the invention, for example as a solder, connection element,

Clamp, flag, seats or the like..

For example, the copper-silver-gold alloy can also be used for one or more soldering points and/or connection element(s), for example strand(s), lug(s) and/or clamp(s) and/or socket(s), for example for connecting the voice coil(s) 12, 13, 14 and/or the respective voice coil-crossover cabling 15 and/or the crossover 16 and/or the crossover-loudspeaker terminal wiring 17 and/or the loudspeaker terminal 18, and/or switch (Not shown in Figure 1) may be formed.

The printed circuit board 23 and/or the elements 24, 25 and/or the mains cable 26 and/or the mains cable plug 27 of the amplifier 20 can also comprise the copper-silver-gold alloy, for example.

timbre analysis

To analyze the timbre of different metals and metal alloys, coils, in particular voice coils and/or choke coils, were produced from the metals or metal alloys to be examined and installed one after the other in a loudspeaker. The timbres produced by the loudspeaker were then determined.

Table 1: Comparative tests using a timbre analysis of one with different

Loudspeakers equipped with voice coils and/or choke coils made of copper, silver and alloys thereof

For the timbre analysis, a first test series based on voice coils according to Table 1, a second test series based on choke coils according to Table 1, and a third test series based on a combination of a voice coil and a choke coil made of similar materials according to Table 1 were carried out.

The coils made from the metals or alloys according to Nos. 1 to 3 and 10 represent comparative examples (CE). The coils made from the alloys according to Nos. 4 to 9 are made from different embodiments of the copper-silver-gold alloy according to the invention and thus represent examples (B) according to the invention.

Table 1 shows that the #1 copper voice coil and/or choke coil resulted in a warm and familiar tone, while the #2 silver voice coil and/or choke coil resulted in a cool and transparent tone.

The voice coil and/or choke coil according to No. 3 made of a copper-silver alloy of 99.9% by weight copper and 0.1% by weight silver resulted in a tight, throaty timbre. The voice coil and/or choke coil according to No. 10 made of a copper-gold alloy of 99.90% by weight copper and 0.10% by weight gold resulted in a warm timbre.

Table 1 shows that the voice coil and/or choke coil of No. 4 is made of a copper-silver-gold alloy of 99.9 wt% copper, 0.07 wt% silver and 0.03 wt% Gold, which serves in particular as an exemplary embodiment according to the invention, surprisingly led to a warm, radiant and elastic timbre with "swing".

Table 1 further shows that Examples (B) Nos. 5 to 9 according to the invention, of which Example (B) No. 5 is based on a copper-silver-gold alloy of 99.98% by weight copper,

0.01 wt% silver and 0.01 wt% gold Example (B) #6 on a copper-silver-gold alloy of 99.97 wt% copper, 0.02 wt% -% silver and 0.01% by weight gold, the example (B) No. 7 on a copper-silver-gold alloy of 99.95% by weight copper, 0.04% by weight silver and 0.01% by weight gold, example (B) No. 8 on a copper-silver-gold alloy of 99.85 wt% copper, 0.10 wt% silver and 0.05 wt% gold and example (B) #9 on a copper Silver-gold alloy based on 99.70% by weight copper, 0.20% by weight silver and 0.10% by weight gold also lead to an advantageous, warm, radiant and elastic timbre. Through copper-silver-gold alloys of > 99.70% by weight up to

<99.98 wt% copper, >0.01 wt% to <0.20 wt% silver, and >0.01 wt% to

<0.10% by weight of gold, based on the total weight of the alloy, a warm, radiant and elastic timbre can thus advantageously be achieved. A higher mass fraction of silver than gold, for example at least twice the mass fraction of silver than gold, seems to have an advantageous effect on the strength of the timbre, in particular the strength of the radiance and elasticity.

In particular, Table 1 shows that inventive examples (B) Nos. 4, 7 and 8, of which Example No. 4 was based on a copper-silver-gold alloy of 99.90% by weight copper, 0.07% by weight % silver and 0.03% by weight gold, Example (B) No. 7 on a copper-silver-gold alloy of 99.95% by weight copper, 0.04% by weight silver and 0.01 wt% gold and example (B) #8 on a copper-silver-gold alloy of 99.85 wt% copper, 0.10 wt% silver and 0.05 wt% -% Gold based leads to a particularly advantageous, warm, radiant and elastic timbre with "swing". Through copper-silver-gold alloys of > 99.85% by weight to < 99.95% by weight copper, > 0.04% by weight to < 0.10% by weight silver and > 0, 01% by weight to < 0.05% by weight of gold, based on the total weight of the alloy, a particularly advantageous, warm, radiant and elastic timbre can be achieved with "Swing".

A comparison of the timbres of Comparative Examples (CE) Nos. 1 to 3 and 10 and Examples (B) Nos. 4 to 9 according to the invention shows that the Comparative Examples (CE) lack radiance, elasticity and, in particular, swing. In view of this, the advantageous warm, radiant and elastic timbre, particularly with swing, of the inventive examples appears to be due to their copper-silver-gold alloys in the specified ranges.

In addition, Examples Nos. 4 to 9 according to the invention, in particular Examples (B) Nos. 4, 7 and 8, show that the alloys according to the invention are particularly advantageously suitable for forming coils, for example inductor coils and/or voice coils, in particular inductor coils . It follows from the above statements that different/different electrical, electronic and/or electrotechnical components and/or electrical, electronic and/or electrotechnical components can have the aforementioned copper-silver-gold alloy. Capacitors, transistors, resistors or coils, in particular choke coils or voice coils, come into consideration here. In particular, the connection points/connecting wires of these parts and/or components can be formed from the aforementioned copper-silver-gold alloy or be or are produced from this aforementioned alloy. Particularly in the case of a capacitor, where the capacitor then has a carrier element or an insulator element, such as a plastic film or a paper film, for example, the carrier element or the insulator element is then in particular on at least one side with the aforementioned copper-silver-gold Alloy provided, in particular metallized accordingly with the aforementioned copper-silver-gold alloy. In this case, in particular, a corresponding layer of the copper-silver-gold alloy in the above-mentioned alloy composition has then been vapour-deposited onto the carrier element or onto the insulator element of the capacitor.
